Definitions

  • the invention relates to a new process for carrying out reactions of carbonyl compounds with organometallic reagents, in particular with Grignard reagents.
  • the selectivity or quality of a chemical reaction is strongly influenced, among other things, by the precise control of temperature and residence time.
  • An example of this is a reaction which is described in patent application DE 44 11 101 A1 (improved process for the preparation of a D - (+) - biotin intermediate "). This is the following reaction:
  • the task is solved by a method for carrying out
  • Reactions of carbonyl compounds with organometallic reagents which is characterized in that a) the organometallic reagent is placed in a solvent and tem perated, b) the carbonyl compound is separately placed in a suitable solvent and tempered, c) the solutions from a) and b) are pumped into a temperature-controlled mini / micromixer for reaction, optionally through a downstream dwell path in the form of a very thin line, which can also be temperature-controlled, with a defined one
  • Residence time is set, d) the emerging reaction mixture is then optionally reacted in a downstream reaction and e) the product mixture obtained is worked up.
  • a plate-shaped micromixer is used as the temperature-controlled mini / microreactor in the process according to the invention, in which the starting materials are optionally brought together in a 180 ° T piece and an intensive one
  • Grignard reagents and organolithium compounds can be used as organometallic reagents in the process. Accordingly, compounds from group 1, 4-dichloromagnesium butane, 3,4,5-trifluoro-1-bromomagnesium benzene and n-butyllithium can be used.
  • a compound selected from the group of aliphatic, cycloaliphatic and heterocyclic ketones can be used as the carbonyl compound.
  • the process according to the invention for converting organometallic compounds with carbonyl compounds selected from the group 4- (pentylcyclohexyl-1) -cyclohexan-4-one (4) and (+) - cis-1,3-dibenzyl-hexahydro-1 H is particularly advantageous thieno [3,4-d] imidazole-2,4-dione.
  • An aprotic nucleophilic solvent can be used as the solvent for the organometallic compound but also for the carbonyl compound.
  • Solvents selected from the group consisting of tetrahydrofuran, diethyl ether, dioxane and dibutyl ether are suitable.
  • the process according to the invention can be carried out at a constant temperature between -40 to +120 ° C., preferably up to 60 ° C.
  • reaction mixture emerging from the mini / micromixer is conveyed with a downstream pump into a storage tank or stirred reactor.
  • a reaction with carbon dioxide or hydrolysis can take place as a subsequent reaction.
  • the reaction can be carried out with intensive mixing with a defined residence time. At the same time, it is ensured under these conditions that the reaction mixture is kept constant at almost a specified temperature during the reaction in the reactor under almost ideal conditions, depending on the starting materials used, between -40 and optionally +120 ° C.
  • the solutions of the educts Grignard reagent and thiolactone are mixed intensively in a continuously operated mini / microreactor at a defined temperature in the production of the above-mentioned intermediate for the production of biotin.
  • the resulting preliminary product after it has been passed through a subsequent very thin, temperature-controlled residence time after it has emerged from the microreactor, is carboxylated with carbon dioxide in a subsequent suitable reactor.
  • the process parameters pressure, temperature and mass flows are measured and controlled at various points
  • the process described is generally suitable for the implementation of organometallic reagents with carbonyl compounds, since the process parameters concentration ratio, pressure, temperature and flow or residence time can be set exactly. With the possibility of precise reaction control and the use of small reactor volumes, a high level of safety is achieved in this way.
